Note: Mouse mode 'move' is needed only on systems where 'MIDDLE-click + drag' doesn't work to move.
Note: The change position mode 'currently selected nodes' is needed only on systems where 'ALT-SHIFT-LEFT-click + drag' doesn't work to change positions in the mouse mode 'change postion'.
Note: Which mouse actions are actually available depends on the system configuration like operating system (Windows, MacOS, Linux), web browser (Internet Explorer, Safari, Firefox), network viewer type (Java, Javascript), and the number of mouse buttons. Some of the actions can be triggered in different ways to make them available on a wider range of systems.
